UNITED STATES JOZEF KUBOVCIK, OF EDWARDSVILLE, PENNSYLVANIA.

CEILING-BOARD SUPPORT.

Application filed November 2, 1922. Serial No. 598,631.

To all whom it may concern:

Be it known that I, Joznr KUBovoIK, a citizen. of the United States, residing at Edwardsville, inv the county of Luzerne and State of Pennsylvania, have invented certain new and useful Improvements in Ceiling-Board Supports; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has for its object to provide a simple and inexpensive device which may be used to advantage for holding sheets of wall board in place while nailing them to the ceiling joist to form the ceiling of a room, thereby overcoming the danger of breaking the board, and obviating the use of a number of workmen, such as would ordinarily be required to support it in place before nailing. V

A further aim is to provide a structure which may be readily knocked down or folded into compact form to facilitate in carrying it from place to place.

WVith the foregoing in view, the invention resides in the novel subject matter hereinafter described and claimed, the description being supplemented by the accompanying drawings.

Fig. 1 is a side elevation showing my invention set up for use.

Fig. 2 is a fragmentary side elevation of the upper end portion of the device, at right angles to Fig. 1.

Fig. 3 is a top plan view.

- Fig. 4- is a detail vertical section on line 4-4. of Fig. 1.

Fig. 5 is a detail horizontal section, as indicated by line 5-5 of Fig. 1.

In the embodiment herein disclosed, the numeral 1 designate a plurality of upwardly converging legs which are hinged to and support a head block 2 provided with a nut 3 at its center. Near their lower ends, the legs 1 have inwardly declined braces 4 which are detachably secured thereto, as indicated at 5, the inner ends of said braces being pivoted to a central block 6. Between the braces 4 and the head block 2, I provide a horizontal stiffening block 7, which is preferably connected with the legs 1 by hooks 9. The center of this block carries a second nut 10 vertically aligned with the nut 3 and the two nuts receive a vertical screw 11.

The upper end of the screw 11 carries a wall board supporting frame which is spaced above the base frame formed by the parts above described, whereby adjustment of said screw will raise or lower said board-supporting frame, as occasion may require, permitting the sheets of wall board to be properly held in place while nailing.

The board-supporting frame above mentioned preferably includes a plurality of upwardly diverging arms 12, hinged at their lower ends to a block 13 carrying a guide 14: for the screw 11.. Above the block 13 is a stiffening block 15 connected with the arms 12 in the same manner as the block 7 is connected with the legs 1. This block 15 is'provided with a socket 16 on its lower side rotatably and removably receiving the upper end of the screw 11.

At their upper ends, the two pairs of arms 12 are connected by a pair of transverse bars 17 and the ends of these bars are connected by parallel side bars 18, bolts 19 with removably countersunk nuts 20 being preferably employed for connecting said bars 17 and 18. The lower ends of the bolts 19 pass through the upper ends of inverted L-shaped metal straps 21 which are detachably connected by bolts 22 with the upper ends of the arms 12. Thus, it will be seen that by removing the bolts 22, the entire top frame formed by the bars 17 and 18 may be removed from. the arms 12. This top frame may then be collapsed without disconnecting the bars 17 and 18, but in order that the device may be more compactly folded, I prefer to totally or partially disassemble said. top frame. It may also be pointed out that if desired, the top frame may remain connected with two of the arms 12 and disconnected from the other of said arms, in which instance it is, of course, necessary to disconnect certain of the bars 17 and 18 in order to permit proper folding.

By disconnecting the block 15 from the arms 12 after totally or partially disconnecting the bars 17 and 18, as above described, it will be seen that the entire upper section of the invention may be folded into compact form. Similarly, by disconnecting the braces 4 from the legs 1 and releasing the hooks 9, the legs 1 may be folded upwardly. If desired, the screw 11 can, of course, be removed from the nuts 3 and 10 and it is, of course, understood that when folding the device the upper frame section is removed from the lower, merely by lifting it from said screw,

Excellent results have been obtained. from the details disclosed and I therefore prefer that these details shall be followed. However, within the scope of the invention as claimed, numerous minor changes may be made.

I claim:

1. In a device of the class described, a frame including a block, a plurality of bars pivoted thereto at one end and inclined outwardly therefrom, a second bracing block disposed in spaced parallelism to the first named block, and means detachably connecting the bars with the bracing block, both of said blocks being provided with central vertically alined means for accommodating a lifting screw.

2-. A ceiling board support comprising an upper board supporting-frame, and a lifting device upon which it is mounted, to gether with a base frame carrying said lifting device, said base frame comprising a head block, upwardly converging legs hinged to said head block, a leg bracing and stiffening block spaced below said head block and engaging said legs, and means for detachably securing said bracing and stiffening block in place.

3. A structure as specified in claim 2, said detachable securing means for said stiffening and reinforcing block consisting of hook and eye connections between said legs and block.

4. A ceiling board support comprising an ,board, a vertical screw upon which said frame is supported, and a base carrying said screw, said base comprising a head block, upwardly converging legs hinged to said head block, a horizontal bracing and stiffening block engaged with said legs below said head block, detachable connections between said bracing and stiffening blocks and said legs,and nuts carried by both of said blocks, said nuts receiving said screw.

5. A ceiling board support comprising a base, a lifting device rising therefrom, and an upper board supporting-frame carried by said lifting device, said frame comprising a block, arms hinged to and rising from said block, a bracing block engaging said arms above said first named block, and means detachably connecting said bracing block with said arms.

6. A structure as specified in claim 5; said lifting device consisting of a screw passing removably through said first named block and removably engaged with said bracing block.

7. A ceiling board support comprising a base, a lifting device rising therefrom, and a board supporting-frame carried by said lifting device, said frame comprising two pairs of upwardly convergingarms, a horizontal top frame, angular straps secured to said top frame and engaging said arms, and means detachably connecting said straps with said arms.

In testimony whereof I have hereunto aflixed my signature.
